Application of demagnetizer to solve magnetite beneficiation process
Demagnetizer magnetic iron ore concentrator unique selection of a magnetic device. Its role is to eliminate magnetic agglomeration, eliminating mineral remanence and flux linkage. In the ore dressing production process, due to the application of magnetic pulleys, fine grain size of the grinding products and multi-stage magnetic separation, the magnetic agglomeration phenomenon is serious, especially the vanadium- titanium magnetite (or roasting magnetite) has a large coercive force. During the selection process, magnetic inclusions and non-magnetic inclusions are prominent. The conventional magnetic separation entrainment of gangue and continuous body content is above 12% (taking Anshan-type roasting magnetite as an example), affecting the quality (grade) and yield of concentrate. Therefore, the method for improving the grade of roasting magnetite ore concentrate is to effectively separate the monomer gangue brought in by the non-magnetic inclusions, and to separate as much as possible the magnetic inclusions, the lean organisms must be effectively dispersed magnetic agglomeration High-efficiency magnetic separation equipment —harmonic wave demagnetizer or magnetic separation column, solves the problem of remnization of ore by reducing the regenerative capacity of the ore by installing a harmonic wave demagnetizer at different positions, and can improve the grade of concentrate due to the annual output. Increase, reduce water, save energy and reduce emissions and create huge economic benefits for enterprises.
A new generation of high-efficiency energy-saving demagnetizer, high demagnetization field, high frequency, obvious demagnetization effect, completely remove the magnetic agglomeration of minerals or magnetic flux without remanence, completely eliminate the influence of magnetic agglomeration on the effective selection of the latter process, can improve Grading, screening efficiency, improving concentrate grade, reducing concentrate water. It plays an important role in stable beneficiation process and comprehensive mineral processing index.
DQ-II type harmonic wave demagnetizer performance and characteristics:
1 Microcomputer intelligent control, fault self-diagnosis, working state protection prompt, double coil alternate work, coil self-cooling. Demagnetization coil seal has good insulation performance, wear-resistant and waterproof, anti-burning, long service life, and can run without slurry empty load. Do not burn the coil.
2 Efficient, environmentally friendly, energy-saving: The demagnetization of the machine is self-optimizing according to the remanence of the material, and the power consumption is small. Only one power saving period is less than one year. Installation, wiring simple control box can be installed in the coil 15 Safe location for easy inspection within meters. The product is stable in operation, safe and reliable, and requires no maintenance. It is suitable for working in the harsh working environment of mines.
3 Supporting coil specifications: common specifications of tubular type Φ108mm, Φ159mm, Φ219mm Φ273mm; dry demagnetizer/belt demagnetizer specifications: T500mm, T650mm, T800mm; special shape, non-standard size demagnetizer can be specially made
